Definition of the Sterling Overnight Index Average (SONIA) 📈§
The Sterling Overnight Index Average (SONIA) is the effective interest rate that banks pay for unsecured overnight loans in the United Kingdom. It serves as a benchmark for various financial instruments and reflects the average rate at which these loans are transacted. Introduced in 1997, it has transformed into the preferred risk-free benchmark interest rate, especially after concerns surrounding the LIBOR (London Interbank Offered Rate) arose.
Key Features of SONIA:§
- Overnight Rates: SONIA is calculated based on actual transactions in the overnight market.
